Scuba regulator dust cap

prusaprinters

Need a dust cap for your second hand regulator? Here it is.Printed using PETG, 0.2mm layers, 3 perimeters, 15% infill and no supports.The original Apeks cap seals against the O-ring. To try the same thing with a printed top surface would surely lead to one finely ground O-ring. This version solves the problem with a piece of bike inner tube. A drop of superglue holds it nicely in place and a smear of silicone grease will ensure a good seal.Included is a template for cutting the inner tube to correct size. Use any liner or similar pen and cut on the inner side of the line.Bright color helps it to stand out in a pile of black gear.
